ARTorch Welding Hoses

ARTorch Welding Hoses

1. Product Overview

Dual welding hoses are designed to safely deliver two separate gas supplies to an oxy-fuel torch:

• Oxygen (O₂)

• Fuel Gas (Acmonetylene, propane, LPG, etc.)

The hoses are bonded together for easier handling and safer routing, ensuring consistent gas flow during welding, brazing, and cutting operations.

These hoses are suitable for professional workshop and light industrial use when installed correctly with approved regulators and safety devices.

2. Intended Applications

Dual welding hoses are used for:

• Light-duty oxy-fuel welding

• Ring and small metal brazing

• General jewelry repair heating

• Medium to high-flow cutting and torch work (with appropriate hose size)

Always select the correct hose diameter and coupling type for your torch and gas demands.

3. Safety Information (READ BEFORE USE)

Oxy-fuel systems involve flammable gas and high-pressure oxygen. Incorrect use can result in:

• Fire or explosion

• Flashback into hoses

• Severe burns or injury

• Equipment failure

Always follow standard oxy-fuel safety procedures.

Mandatory Safety Equipment

Always use:

• Proper gas regulators

• Flashback arrestors (recommended on both torch and regulator ends)

• Leak detection spray or soapy water testing

• Eye protection and heat-resistant gloves

Never use oil or grease on oxygen fittings.

4. Hose Identification

Dual hoses are typically colour coded:

• Green or Blue: Oxygen line

• Red: Fuel gas line

Never interchange oxygen and fuel hoses.

5. Installation & Connection

Step 1 — Inspect Before Connecting

Before each use, check:

• No cracks, cuts, blisters, or burn marks

• No loose fittings

• No kinks or crushed sections

• Couplings are clean and undamaged

Do not use a damaged hose.

Step 2 — Connect to Regulators

Attach hoses securely to the correct regulator outlets:

• Oxygen hose → Oxygen regulator

• Fuel hose → Fuel regulator

Tighten couplings with the correct wrench. Do not overtighten.

Step 3 — Connect to Torch

Attach hoses to the torch inlet connections, ensuring correct gas alignment.

6. Leak Testing Procedure

After connection:

1. Slowly open cylinder valves

2. Pressurise the system through the regulators

3. Apply leak detection solution to all joints

4. Check for bubbling or pressure drop

If leaks are found:

• Close cylinders immediately

• Vent gas safely

• Repair or replace fittings before use

Never use a flame to check for leaks.

7. Correct Use During Operation

• Keep hoses away from hot metal, sparks, and open flame

• Do not drag hoses across sharp edges

• Avoid twisting or tightly bending hoses

• Maintain stable torch gas pressure as per manufacturer settings

Do not exceed the rated working pressure of the hose.

8. Flashback Prevention

Flashback is a dangerous event where flame travels backwards into the hose.

To reduce risk:

• Use flashback arrestors

• Purge hoses before lighting

• Maintain correct gas pressures

• Never operate with clogged torch tips

If a flashback occurs:

1. Shut off torch valves immediately

2. Close cylinder valves

3. Allow system to cool

4. Inspect hoses and torch before reuse

Replace hoses if there is any doubt.

9. Storage & Maintenance

After use:

• Close cylinder valves fully

• Bleed pressure from hoses

• Store hoses loosely coiled (never tightly wound)

• Keep away from sunlight, oil, solvents, and heat sources

• Hang hoses off the floor where possible

Do not tape, splice, or patch welding hoses — replace damaged hoses immediately.

10. Replacement Guidelines

Replace the hose if you observe:

• Cracking or brittleness

• Burn marks or melted areas

• Damaged couplings

• Persistent leaks

• Hose stiffness or deformation

Hoses are consumable safety components and must be kept in good condition.

11. Disclaimer

This hose must be used only by trained persons familiar with oxy-fuel welding equipment. Always follow local safety regulations and torch manufacturer guidelines. CapeTools assumes no liability for misuse, incorrect installation, or operation outside intended applications.
